Hau Wong Temple (侯王古廟) Kowloon City. The place is a little small but it’s very historical. This temple was built during the Ching dynasty. You can click here for further information on this temple.
It’s right at the coner of Junction Road and Tung Tau Tsuen Road. If you look at my previous post on Kowloon Walled City, it’s on the same stretch of the road.
